摘要
以王水对试样进行消解，用双硫腙分光光度法测定藏成药“佐志达协”中汞的含量，测定结果与冷原子吸收法比较十分接近，加标回收率９８％～１１０％，在０．０～７．０微克汞间线性关系良好．
Mercury content in the traditional Tibetan medicine,labeled “Zuo Zhi Da Xie”,was measured by dithizone spectrophotometric method with the samples dissolved in aqua regia.The result showes that the recovery of added standard sample was about 98%-110% and there is a good linear relationship at mercury content ranging from 0.0-7.0μg.This result is in very good agreement with that of cold atomic absorbing method.
